We moved in 3 months ago. As in previous place, there are lots of local cats strolling around, but this particular cat started coming to our garden more and more, to the point that other cats don't pass anymore. I used to dislike cats, but this one is friendly, lovely, looks clean and looked after, and more over after stroking her several times, comes at least 3 times a day and meows to be stroked or let in. DS let her in 2 times by mistake (or the cat invited herself over), but it was taken out to the garden immediately. Every so often when I go downstairs, I can see it longingly sitting with her face pressed against the garden door longingly, even when there is noone downstairs, she just sits there waiting for someone to come and I feel so sad for her. I would love to invite her inside, but I respect her owners (whoever she/he is) and I keep her strictly inside. The thing it makes me emotional and so sad for her. As I said I didn't even like cats before I met her!
Should I just keep it this way?
